| 41 | Dispenser with suction chamber | US10993807 | 2004-11-20 | US20060108380A1 | 2006-05-25 | Nick Ciavarella |
| A dispenser for dispensing a soap product includes a soap pump, a dispensing nozzle, and an expandable and contractible suction chamber. The dispensing nozzle has an outlet for dispensing soap, and the suction chamber is disposed between the soap pump and the dispensing nozzle. The suction chamber is expandable and contractible in volume and is predisposed to an expanded volume. Actuation of the soap pump causes the suction chamber to contract to a contracted volume that is less than the expanded volume to which it is predisposed, and soap is forced through the suction chamber and the dispensing nozzle to the outlet where it is dispensed. Soap that has not been dispensed at the outlet resides in the dispensing nozzle after actuation of the soap pump, and this residual soap is sucked back into the suction chamber during a return of the suction chamber to the expanded volume to which it is predisposed. | ||||||
| 42 | Device for dispensing a medium such as a toothpaste or a gel | US10394900 | 2003-03-22 | US20040182885A1 | 2004-09-23 | Ray C. Morrison; Gerald A. Sferruzza JR. |
| The invention is a device for use by a person to dispense a medium such as a toothpaste or a gel from a disposable container. The device comprises a pump unit having medium and air pistons engaged with medium and air cylinder portions, respectively, thru a compression stroke and an intake stroke. The device further comprises an intake unit engaged with the pump unit. The intake unit comprises an inlet portion engageable with the container. The intake unit further comprises an intake valve operable from a closed position to an open position where the inlet portion is in communication with the medium cylinder portion. The device further comprises an exhaust unit engaged with the pump unit. The exhaust unit comprises a nozzle portion. The exhaust unit further comprises an exhaust medium valve operable from a closed position to an open position where the medium cylinder portion of the pump unit is in communication with the nozzle portion. The exhaust unit further comprises an exhaust air valve operable from a closed position to an open position where the air cylinder portion of the pump unit is in communication with the nozzle portion. The device further comprises an actuation unit engaged with the pump unit. Activation of the actuation unit causes the medium and air pistons to cycle thru a compression and an intake stroke. At steady state operation, the compression stroke of the medium piston causes a portion of the medium to move thru the exhaust medium valve to the nozzle portion and the compression stroke of the air piston causes a portion of the air contained in the air cylinder portion to expand thru the exhaust air valve to the nozzle portion to dispense a consistent and defined amount of medium. The intake stroke of the medium piston causes a portion of the medium contained in the intake unit to be drawn into the medium cylinder portion of the pump unit. The intake stroke of the air piston causes air to be drawn into the air cylinder portion of the pump unit. | ||||||

| A metering valve includes a valve stem co-axially slidable within a chamber body. The chamber body and the valve stem define a metering chamber. An outer and an inner annular seal is provided operative between a respective outer end and an inner end of the chamber body and the valve stem to seal the annular metering chamber there between. The inner seal comprises a wiper element. | ||||||
| 44 | Volumetric pump | US09863966 | 2001-05-23 | US06398081B2 | 2002-06-04 | Luigi Bassi; Stefano Oggioni |
| A volumetric pump for dispensing a controlled and continuous flow of viscous fluid. The pump according to a preferred embodiment of the present invention can ideally dispense from a minimum of 1 mg/sec to 1 g/sec for fluids with a viscosity from 2,000,000 cps (Centipoise) down to 10,000 cps. Such flexibility in the range of viscosity extends the application fields of this pump to microelectronics as well as automotive and consumer products manufacturing. Two cams mounted with an opposing position of 180° on the same shaft generate an alternate motion of two concentric pistons. The alternate movement of the external piston in one phase pumps out the material through a dispensing needle and allows in the returning phase the viscous fluid to be charged in the dispensing chamber from the feeding container. The alternate movement opens and closes the vents during the different working phases. | ||||||
| 45 | Dispensing device for a measured volume of liquid | US163994 | 1993-12-07 | US5381930A | 1995-01-17 | Peter Kalabakas |
| A dispensing device for dispensing a measured volume of liquid from a body of liquid contained in a container, which includes a receptacle for receiving an unmeasured excess volume of liquid from the body of liquid and a conduit to connect the container to the receptacle. The conduit permits liquid to flow from the body of liquid into the receptacle when a reduced pressure is created in the receptacle. The device further includes a lid to fit over the receptacle so as to be displaceable relative to the receptacle from a closed position to a dispensing position, the arrangement being such that relative displacement between the lid and receptacle can create a pressure differential between the container and the receptacle to cause liquid to flow from the body of liquid in the container to the receptacle. A part of the conduit serves to adjust the unmeasured excess volume of liquid in the receptacle to the measured volume. | ||||||
| 46 | Dosing cap | US268416 | 1988-11-08 | US4941598A | 1990-07-17 | Lawrence E. Lambelet, Jr.; Thomas A. Frazier |
| Apparatus for dispensing predetermined amounts of viscous product. The apparatus has a conduit which is telescopically received with a cap. The cap and conduit define an expandable dosing chamber which expands to a predetermined maximum volume when product is introduced into the chamber through the conduit. A check valve prevents back flow of product through the conduit. Collapsing the chamber from its maximum volume to a minimum volume dispenses the product from the dosing chamber. | ||||||

| A volumetric metering device comprising a housing, a butterfly gate control unit and an adjuster to adjust the volume of a metering chamber whose operation is controlled by the butterfly gate control unit between a first condition to load the metering chamber with particulate material and a second condition to discharge the particulate material from the housing. | ||||||

| A method and apparatus for dispensing small quantities of viscous materials in a reliable and accurately repeatable manner are described. A deformable tube which couples material in a reservoir to a discharge port is pinched by a valve at the same time the reservoir is pressurized. The material is dispensed in correspondence with the amount of reduction of the tube volume by the pinch valve. A simultaneous depressurizing of the material in the reservoir and the opening of the pinch valve enables a suck-back for a crisp cut-off of the material. | ||||||
| 49 | Liquid handling apparatus | US573490 | 1975-05-01 | US3995667A | 1976-12-07 | Michael W. Brandt |
| Liquid handling apparatus adapted for transferring a measured quantity of toxic liquid pesticide from a storage container into a tubular body and for transferring the toxic liquid pesticide from the tubular body into a pressurizable container. The storage container, the tubular body, and the pressurizable container each has an inwardly opening check valve in an opening communicating with the interior thereof. Each check valve has a stem extending outwardly therefrom. The stem on the check valve communicating with the interior of the storage container is positionable in abutting relation with the stem on the check valve communicating with the interior of the tubular body for opening the respective valves to permit transfer of liquid from the storage container into the tubular body. The stem on the check valve communicating with the interior of the tubular body is positionable in abutting relation with the stem on the check valve communicating with the interior of the pressurizable container to permit transfer of liquid from the tubular body into a pressurizable container. | ||||||
